This article is the conclusion of our old ‘key ideas’ series, which we stopped updating in 2023. We’d suggest reading the article in our advanced series instead.

We believe that some of the career paths open to you likely have over 100 times more positive impact than other paths you might take.

Why? In our key ideas series, we’ve shown that you can have more impact by:

  1. Finding a bigger and/or more neglected problem
  2. Finding a path that gives you a bigger opportunity to contribute
  3. Finding work that fits you better

We’ve also shown that there are big differences for each factor:

On top of that, you can further increase your impact by having a good career strategy, such as by striking the right balance between investing in yourself and having an impact right away.

Then also note that the differences multiply together, rather than merely add up.

For instance, if you can find a problem where additional resources are three times as effective, and find a path where you can make three times the contribution, then you’ll have nine times as much impact.

One implication of this is that if a path scores near zero on one of the factors, then its overall impact is low. This means it’s very easy to ‘give up’ most of your impact by not paying attention to all the factors.

But this also means that if you can make improvements on one dimension, it’ll multiply with improvements you make on the other dimensions.

And we’ve tried to show in the series that despite the huge uncertainties involved, it often seems possible to find an option that’s 10 times better on each factor. If you could find a path that’s 10 times better on each factor, then when multiplied together, the total difference could be 1,000 times.

In practice, it’s often not possible to find an option that’s better in every dimension. For instance, by changing the problem area you’re working on, you might have less confidence in your fit.

There are also some reasons to be sceptical of claims of outsized differences that we’ve covered elsewhere in the series, such as regression to the mean and epistemic humility.

All considered, however, we think it’s often achievable to find a path that is 10 times more impactful than what you’re currently focused on, and sometimes over 100 times more impactful.

It’s easy to gloss over the significance of a 100 times difference, but let’s appreciate for a moment just how much it matters. It could mean saving 100 times more lives, reducing carbon emissions 100 times as much, or making 100 times more progress reducing the biggest risks facing humanity.

These differences may not be the only ethically relevant factors, and everyone has priorities in life besides moral ones, but they do really matter.

Here’s another way to see their significance: if it’s possible to find an option that’s 100 times higher impact than your current best guess, then 10 years in that path would achieve what could have otherwise taken people like you 1,000 years. You could then spend the next 30 years on a beach or doing whatever you’d find most personally fulfilling, and still have done far more to help others.

So this analysis shows that it could easily be possible to find a path that’s both higher impact and more personally satisfying than your current trajectory.

How is it possible that such big differences in impact exist?

One reason is the massive economic and technological bounty of the Industrial Revolution, which means that today, many ordinary citizens of rich countries have what would have been kinglike wealth and power in previous centuries.

World average income

And advancing technology may make the next century one of the most important in history.

Our generation can wreck the climate for thousands of years, or we can build a sustainable economy. We can continue to expand factory farming, or we can eradicate it. We can allow new technologies like nuclear weapons to end civilisation, or we can usher in a future better than we can imagine — and be good stewards for all future generations.

Our aim is to help people like you understand this new power. If you have the good fortune to have options about how you spend your career, you can help change the course of history on these vital issues.

This is not an easy path, but it is a worthwhile one.

Finding the best path for you requires exploring, investing in yourself, taking risks, and making hard tradeoffs.

We’ve often felt racked with uncertainty about what to do, and overwhelmed at the scale of the issues. But we’ve also found meaning and satisfaction in our efforts, especially as more and more people have united around them.

We still have a lot to learn, but we hope that by sharing what we’ve learned so far we can help you avoid the mistakes we’ve made, and speed you along your path to an impactful career.

You have 80,000 hours in your career. Make them count.
